Been working just fine. Had like 6 months.
Just now I noticed it has been churning away longer than usual.
Look at the TM drive.
The ONLY backup shown is 2022-01-17..
Nothing has changed on my computer in weeks.
No messing with system stuff or hardware.
Just wanted to offer you a few articles and troubleshooting tips that I have been using for Time Machine backup issues.
Both of these articles are an excellent source of information to really give you an idea of what goes on "behind the scenes" during the TM backup process:
Although the second article refers to macOS Catalina, it is still valid with macOS Monterey.
FWIW, I have found the Mints app invaluable in troubleshooting TM. I used to do this via commands in Terminal, but the app makes this far easier. Hopefully, it will shed some light on what's going on with TM on your Mac. Basically, I have found TM to have become less reliable since macOS Sierra. Initially, with just backups to the Time Capsule, but now with directly attached drives as well. So far, TM backups to my Synology NAS has been "rock solid." As such, although I continue to use TM, I rely on other backup tools (like Carbon Copy Cloner) in addition.
No, I didn’t do anything after the last
backup
I do glance at T-MOBILE every few days and it seemed fine.
It went back like 6 months or so.
Now…
So here’s the latest.
one backup two days ago and one is going on now. Very small.

If you open Time Machine Preferences does it show our backup disk?
Does the disk show in Finder?
Can you access the disk via Finder and via Enter ™?
Manually start a backup and open TM preferences and observe the progress of the backup. Any errors? Messages?observe
Yes it shows backup disk
Yes it shows in Finder
Yes I can enter TM.
I stopped it the restarted it and it shows Changed 18,945,623 items. (and counting) This seems to be new in Monterey.
It shows 43% progress. Currently backed up like 224GB.
It an 8TB drive
Backups.backups b is about 990GB
There is about another 222GB in another folder
The drive shows 516GB available.
So it seems the previous data is still there on the drive but not showing in Finder or in TM
It's churning away, doing backups, but the backup shows no changes.
Still only 1 backup shown.
I turned off TM, ran Disk First Aid (it was okay) then restarted the computer and turned on TM.
Right now, its "Preparing Backup...'
If you have not, try upgrading to macOS 12.2, the problem you're having may be related to this thread, which was fixed in 12.2: Time Machine "Waiting to Compete First Ba… - Apple Community
Did you do anything to the Mac right after the last completed backup?
Periodically look at the progres of the backup and see when it stops
Turned off auto backup then did a manual backup. It worked okay.
Then I enabled auto backup and it seems to be working okay
What happened to all my TM backups?
